Whether you are traveling in the U.S. or having a staycation this Saturday, be sure to include some culture. September 28 is Museum Day Live! (aka Free Museum Day), when museums all over the country open their doors without charging admission.

Enjoy.

In this lull between fun summer TV like “True Blood” and the fall premieres of network television shows, many people have been binge watching the Netflix comedy, “Orange is the New Black.” Set at a women’s prison in Rockland County, New York, the series has generated new interest in jail. (From the outside, at least.) Here are five notable prison museums around the world with flexible visiting hours for an easy escape.

Alcatraz, San Francisco, CA
Built as an “inescapable” prison on an island off San Francisco, Alcatraz has had quite a few famous inmates, including Al Capone. The federal prison was closed in 1963 and has been a museum for several decades. In addition to the prison museum, it also has the country’s oldest lighthouse and a permanent exhibition on the historic Native American occupation. Tickets are a steep $30 and up per adult, but they include transportation, since you can’t make it off “the Rock” alive.Eastern State Penitentiary, Philadelphia, PA
Another stop on Al Capone’s “jail tour,” this Center City Philadelphia jail has been the set for several films including “Twelve Monkeys” and the Transformers sequel, and many TV shows about ghosts and jails. The self-guided audio tour (narrated by Steve Buscemi!) details the history of the prison, active from 1829 to 1969. Regular tickets are $14, and look out for special events; the Halloween Haunted House is especially popular.

Robben Island, Cape Town, South Africa
The isolation of the small island near Cape Town made it a fitting site for a leper colony, a military training station and a place for political prisoners. Nelson Mandela was the most famous of former inmates for 18 years; he was one of dozens imprisoned during apartheid. Tickets are about $22, including ferry transportation to and from the mainland, a bus tour of the island and “interaction” with a former prisoner. President Obama visited the island and museum this summer, and was “deeply humbled” by the experience.

Tuel Sleng, Phnom Penh, Cambodia
The secret prison of Pol Pot, dictator of Cambodia in the 1970s and leader of the Khmer Rouge, Tuel Sleng is now a museum cataloging the genocide perpetrated there. The museum contains the 6,000 detailed photographs and records of inmates left by prison staff, though as many as 30,000 were said to have been detained, tortured and murdered there. The museum is preserved as it was found in 1979, and is an important site, along with the “Killing Fields,” documenting and memorializing the victims of this dark regime.

Why spend your summer vacation on subways and buses when you could be out exploring places on two wheels?

Thanks to an explosion in bike-share systems and a general appreciation for bike culture, making cycling a central part of your travels is becoming easier and easier. You don’t have to throw down, pack your bicycle and head off on a full cycle tour to get the pleasure of seeing a place on two wheels; there are plenty of cities around the world that are bike-friendly and perfect for anyone who enjoys the thrills of riding in a new place.

Here are the ten best places to explore by bike.1. Amsterdam
There’s no denying that if you’re a bike lover, Amsterdam should be at the top of your list. Here people are practically born on bicycles, and if you want to experience the city like a real local, there’s no better way. Start off in the Jordaan district, rent a bike at the friendly Bike City and get ready to master the dance that is cycling in the Netherlands.

3. ​Portland, Oregon
Beer, baristas and bikes; it’s the Portland trifecta. You can get all three at Velocult, the city’s hub for bike related events and general fun. If you’re downtown you should be sure to hit up the Courrier Coffee Bar, opened by one of the city’s favorite pedal-delivered craft roasting companies. Add Trailhead to the list as well, another bike-powered artisan roaster. And when you’ve had enough pedal-powered caffeine for the day, take your bike, roll over to the bike-centric bar Apex and drink one of their 50 beers on tap.

4. Paris
Ok, so Paris might not be the first place that comes to mind on the list of bike-friendly places – you do have to do a lot of scooter and pedestrian dodging – but thanks to the successful Velib bike-share system, cycling is a big part of Parisian culture. The key in Paris is to identify that bike paths; you’ll find separated lanes around the city that make two-wheeled Paris a true delight.

5. San Francisco
Don’t let the hills scare you off. Through the late spring and early fall you can take advantage of Sunday Streets, a collection of events that closes off streets to cars in different neighborhoods around the city, and in Golden Gate Park there are car-free Sundays and Saturdays. For a longer adventure, make your way to Marin County.

6. Berlin
Berlin is in the top 10 of bike blog Copenhagenize’s bicycle-friendly cities and with good reason. Around 13% of the population ride their bike on a daily basis, and in some neighborhoods it’s as high as 25%. There’s the 1st Bicycle Gallery which is all about showcasing gorgeous bicycles . There’s an online route planner you can use to facilitate your ride, and if you want a different look at one of the city’s most iconic landmarks, cycle the Berlin Wall Trail, tracing the former wall.

8. Barcelona
Beach and bikes; it’s no surprise that Barcelona is popular with budget-savvy travelers looking for a little warm weather and outdoor strolls. There are over 100 stations for the city’s Bicing program, and a variety of rental and tour options. Top that ride off with some tapas and you have the perfect day.

9. Montreal
Montreal is the place to be if you’re a cycle lover. There are trails, separated lanes and designated biking streets, easily navigable on PedalMontreal. The city is also the gateway to Quebec’s Route Verte, boasting over 5,000 kilometers of bikeways all over the region along with bike-friendly accomodations. You may need a few weeks.

10. Bogotá
Bogotá’s CicloRuta s one of the most extensive in the world. Given that a very small percentage of the local population has access to cars, bicycles make economic sense. If your destination is too far to ride to, the network of bike lanes connects well with the local transportation system, complete with bike parking at several designated stops. As the city’s ex mayor Enrique Peñalosa said, “I think the future of the world has to do with bicycles.”

In the modern world, it’s easy to become immune to traffic. We spend so much time in and around cars that seeing them becomes second nature. Instead of standing out, they simply create the background.

Nighttime is different. That time of day when lights shine and glitter and the urban jungle takes on a whole new look. Flickr user Jason Rodman snapped this nighttime traffic shot and titled it “Chutes and Ladders,” a fitting name for the traverse of red and white in the midst of a city.
